HAL Tejas

This is a timeline of the development of the HAL Tejas, a light-weight, multirole fighter aircraft manufactured by Hindustan Aeronautics Limited.

1960s[edit]

1969[edit]

  • Indian government accepted the recommendation by its Aeronautics Committee that Hindustan Aeronautics Limited (HAL) should design and develop an advanced technology fighter aircraft around a proven engine

1970s[edit]

1975[edit]

  • HAL completed design studies in 1975, but the project fell through due to inability to procure the selected "proven engine" from a foreign manufacturer and unfulfilled IAF requirements.

1980s[edit]

1983[edit]

  • DRDO obtained permission to initiate a programme to design and develop a Light Combat Aircraft

1984[edit]

1985[edit]

  • IAF submits Air Staff Requirements (ASR) for LCA in October 1985. This was initiated by the then Air Chief Marshal Idris Hassan Latif.

1986[edit]

  • Government allocates 575 crores for the LCA programme.
  • Programme to develop an indigenous powerplant (engine) was launched at GTRE.

1987[edit]

  • Project definition commenced in October 1987 with French Dassault Aviation as consultants.

1988[edit]

  • Project definition completed in September 1988.

1989[edit]

  • Government review committee expresses confidence in LCA programme. It was decided that the programme will be carried out in two phases.

1990s[edit]

1990[edit]

  • Design of LCA was finalised as a small delta winged relaxed static stability aircraft.
  • Phase 1 of the development was commenced to create the proof of concept system. Financial problems within India prevented full scale operations from starting.

1993[edit]

  • Full funding started from April 1993 full-scale development work for phase 1 started in June.

1995[edit]

  • First technology demonstrator, TD-1, rolled out on 17 November 1995 and was followed by TD-2 in 1998. However, technical problems in flight control systems and structural deficiencies plagued the prototypes and they remained grounded.

1997[edit]

  • Multi-Mode Radar (MMR) for LCA design work started at HAL’s Hyderabad division and the LRDE.

2000s[edit]

2001[edit]

  • 4 May - LCA’s maiden flight successfully completed by Technology Demonstrator TD-1, on 2001. Prime minister Atal Bihari Vajpayee renames LCA as Tejas.
  • Development assistance sought from Snecma on the Kaveri engine.[1]

2002[edit]

  • 6 June - TD-2 makes a successful maiden flight.
  • MMR system was reported to be not working as per the criteria laid down in requirements.

2003[edit]

  • 25 November - PV-1 makes a successful maiden flight.

2005[edit]

  • 1 December - PV-2 makes a successful maiden flight.

2006[edit]

  • 13 May - The PV-2 went supersonic for the first time
  • 14 May - The PV-2 went supersonic again, but this time in a weaponised state (i.e., carrying weapons such as missiles and an internal gun).
  • 1 December - The PV-3 flew for the first time for 27 minutes at an altitude of 2.5 km and at a speed of Mach 0.8. The PV-3 was equipped with a more advanced pilot interface, refined avionics and higher control law capabilities compared with the previous versions.

2007[edit]

  • 25 April - The first Limited Series Production LCA (LSP-1) made its first flight and it reached a speed of Mach 1.1.
  • PV-2 and PV-3 underwent sea-level trials at INS Rajali Naval Air Station, Arakkonam to study the effects of flying at sea-level, as all earlier trials have been conducted at Bangalore which is 3,000 feet (910 m) above sea-level.[2][3] The reliability of the LCA systems under the hot and humid conditions, as well as low level flight characteristics was tested.[4][5] It is due to this intense flight testing schedule that the LCA was not able to fly at the Paris air show-2007, as was originally planned.[6]
  • 7 September - Tejas Prototype Vehicle (PV-1) made a successful maiden flight with two 800 litre drop tanks.[7][8]
  • 25 October - Tejas PV-1 fired a Vympel R-73 missile for first time. The trials were conducted off the Goa coast at INS Hansa Naval Air Station.[9]
  • 11 December - LITENING targeting pod was successfully tested on Tejas PV-2.[10]

2008[edit]

HAL Tejas high-altitude trials at Leh successfully completed by December 2008.
  • 7 February - Tejas Prototype Vehicle (PV-1) made a successful flight powered by fuel from two 800 litre drop tanks. It made a one hour and 24 minute long sortie. On internal fuel LCA can perform a 40-minute sortie.[11]
  • April - First Flight with HMDS[12]
  • LCA Tejas prototypes PV-2 & PV-3 underwent hot weather flight trials at Air Force Station, Nagpur from 28 May 2008 to 4 June 2008. The trials were declared successful.
  • 16 June - Tejas second Limited Series Production LCA (LSP-2) made its first flight and it reached a speed of Mach 1.1.
  • 7 November - LCA Prototype Vehicle-3 made first successful night flight.[13]
  • 13 December - PV-3 and LSP-2 completed the high altitude trials at the Leh air base.[14]

2009[edit]

  • 22 January - Tejas completed 1000 flights.[15]
  • February - the live bombs test were successfully carried out.[16]
  • October - PV-3 and LSP-2 completed visual target elimination and air-to-ground weapons delivery trials.[17]
  • 26 November - Two seater (Trainer) version of Tejas(PV-5) made its maiden flight on 26 Nov 09.[18]
  • 7 December - Tejas passed flight flutter test diving from an altitude of four kilometers to almost sea level at 900 feet (270 m). Tejas recorded a speed over 1350 km/h. These tests were conducted at INS Hansa, Goa.[19]
  • 15 December - Indian government sanctioned Rs 8,000 crores to begin production of the fighter jet for the Indian Air Force and Indian Navy.[20]

2010s[edit]

2010[edit]

  • 23 April - LCA Tejas LSP-3 Makes Maiden Flight. LSP-3 is almost the final configuration including the new air-data computers, Hybrid Multi Mode Radar, new communication and navigation equipment and radar warning receiver. With this the LCA programme has completed 1350 test flights logging about 800 flying hours.[21]
  • 2 June - LCA Tejas LSP-4 Makes Maiden Flight. The flight marks the first time for a Tejas aircraft flying in the configuration that will be finally delivered to the Indian Air Force.[22] In addition to the Hybrid MMR, the aircraft also flew with a functioning Countermeasure Dispensing System [23]
